Preparation and Use of Porous Poly(-Hydroxyester) Scaffolds for Bone Tissue Engineering
Time of Update: 2020-12-29
Current options for bone replacement include autografts, allografts, metals, ceramics, and polymeric bone cements.
Ceramics suffer from slow integration and remodeling, and wear-debris from nondegradable polymeric implants may evoke chronic inflammation.
Finally, metallic implants may cause atrophy of surrounding tissue through stress shielding, requiring corrective procedures.

Processing of Resorbable Poly--Hydroxy Acids for Use as Tissue-Engineering Scaffolds
Time of Update: 2020-12-13
Polyglycolide (PGA) and poly- l -lactide (PLLA) homopolymers and their copolymers (PLGA), as well as polylactic acid stereocopolymers produced usingl -,d -, orDL -lactides and rasemic polymer copolymer PLDLA are all poly (α-hydroxyacids) ( 3 ).
Poly (α-hydroxy acids) can be polymerized via condensation, although only low mol-wt polymers are produced.
